TrayIcon hiding

[Jon 775]

I've just added the tray icon hiding code at least that's one thing less for people to moan at me for

Even if the first line of the script is:

AutoItSetOption("TrayIconHide", 1)

I've made it flash the icon up for about 750ms before hiding takes place. Anyone with a legitimate use won't mind that. (Of course the source is available for hacking but should be fine for most people).
